如何总计SQL结果

Question

如何将结果合计为一个记录而不是多个item_id实例。相反，我需要为每个项目开具发票总额。

select
inv_mast.default_product_group,
inv_mast.item_id,
inv_mast.item_desc,oe_hdr.order_date,
oe_line.qty_invoiced,
oe_line.extended_price 

from
job_price_hdr

join oe_hdr on oe_hdr.job_price_hdr_uid = job_price_hdr.job_price_hdr_uid 
join oe_line on oe_line.order_no = oe_hdr.order_no
join inv_mast on inv_mast.inv_mast_uid = oe_line.inv_mast_uid

where
oe_line.qty_invoiced> 0
and
oe_hdr.customer_id = 100080
and
default_product_group = 'FAST'

order by
inv_mast.item_id

试试这个，如果您需要更多信息，请告诉我

 select
    inv_mast.item_id,SUM(oe_line.qty_invoiced)
    from
    job_price_hdr

    join oe_hdr on oe_hdr.job_price_hdr_uid = job_price_hdr.job_price_hdr_uid 
    join oe_line on oe_line.order_no = oe_hdr.order_no
    join inv_mast on inv_mast.inv_mast_uid = oe_line.inv_mast_uid

    where
    oe_line.qty_invoiced> 0
    and
    oe_hdr.customer_id = 100080
    and
    default_product_group = 'FAST'
    GROUP BY inv_mast.item_id
    order by
    inv_mast.item_id
